MLD
MLD is an acronym for Multicast Listener Discovery for IPv6. MLD is used by IPv6 routers
to discover multicast listeners on a directly attached link, much as IGMP is used in IPv4.
The protocol is embedded in ICMPv6 instead of using a separate protocol.
MVR
Multicast VLAN Registration (MVR) is a protocol for Layer 2 (IP)-networks that enables
multicast-traffic from a source VLAN to be shared with subscriber-VLANs.
The main reason for using MVR is to save bandwidth by preventing duplicate multicast
streams being sent in the core network, instead the stream(s) are received on the MVR-
VLAN and forwarded to the VLANs where hosts have requested it/them(Wikipedia).
N
NAS
NAS is an acronym for Network Access Server. The NAS is meant to act as a gateway to
guard access to a protected source. A client connects to the NAS, and the NAS connects
to another resource asking whether the client's supplied credentials are valid. Based on
the answer, the NAS then allows or disallows access to the protected resource. An
example of a NAS implementation is IEEE 802.1X.
NetBIOS
NetBIOS is an acronym for Network Basic Input/Output System. It is a program that
allows applications on separate computers to communicate within a Local Area Network
(LAN), and it is not supported on a Wide Area Network (WAN).
The NetBIOS giving each computer in the network both a NetBIOS name and an IP
address corresponding to a different host name, provides the session and transport
services described in the Open Systems Interconnection (OSI) model.
NFS
NFS is an acronym for Network File System. It allows hosts to mount partitions on a
remote system and use them as though they are local file systems.
NFS allows the system administrator to store resources in a central location on the
network, providing authorized users continuous access to them, which means NFS
supports sharing of files, printers, and other resources as persistent storage over a
computer network.
NTP
NTP is an acronym for Network Time Protocol, a network protocol for synchronizing the
clocks of computer systems. NTP uses UDP (datagrams) as transport layer.
O
OAM
OAM is an acronym for Operation Administration and Maintenance.
It is a protocol described in ITU-T Y.1731 used to implement carrier ethernet functionality.
MEP functionality like CC and RDI is based on this

Optional TLVs.

A LLDP frame contains multiple TLVs
For some TLVs it is configurable if the switch shall include the TLV in the LLDP frame.
These TLVs are known as optional TLVs. If an optional TLVs is disabled the
corresponding information is not included in the LLDP frame.
